“He was a pleasure to work with, a super-talented musician with a lovely sense of humor,” McCartney said of his former bandmate. “The solo he played on ‘My Love’ was a classic that he made up on the spot in front of the orchestra. Our deepest sympathies from my family to his.”

McCullough only played on one Wings album, 1973’s Red Rose Speedway. He also appeared on the legendary James Bond theme “Live and Let Die” that the band recorded for the film of the same name.

Outside of Wings, the guitarist had a varied career that launched in 1961. He was part of the psychedelic band the People before later joining Joe Cocker’s Grease Band and performed during Cocker’s legendary set at Woodstock. During his time and with the members of the Grease Band, McCullough played guitar on the album version of Andrew Lloyd Webber and Tim Rice’s rock opera Jesus Christ Superstar.

Following Wings, McCullough became a session musician playing with Eric Burdon, Marianne Faithfull, Roy Harper and Donovan. His voice be heard speaking at the end of Pink Floyd’s “Money” on The Dark Side of the Moon where he says: “I don’t know. I was really drunk at the time.”

As a solo artist, McCullough released 11 albums including his 1975 debut Mind Your Own Business and his final release, 2012’s Shabby Road.
